THE BUICK GSX

Over-looked and under-appreciated, Buick's GSX was a true American "Muscle car" in every sense of the word. GM's usually staid Buick Division had watched with frustration while its corporate siblings – to say nothing of Chrysler and Ford – seized the youth market. Buick's image was of building dull cars for older drivers, but by the end of the 1960s the Flint-based division lobbied for its own opportunity. Buick already had the perfect engine in hand, a massive 455-cubic inch beast that was part of the "Big Block" family. The 455 had already found a home in Buick's heavy full-sized cars, but the company's product managers wanted to do what Pontiac, Chevrolet, and Oldsmobile had done, which was to stuff a big-inchV8 into its intermediate-sized Skylark coupe and play with the big boys. Buick finally received a green light, and the GS455 appeared in 1970. Buick advertised the hot GSX, with its own eye-catching graphics package, as its reply to Pontiac's GTO Judge and Oldsmobile's 4-4-2 W-30. The GSX advertised a very conservative 350 hp, and the "tuned" GSX Stage 1 was officially rated at 360 hp – in reality it was more like 425 - with the help of a higher-lift cam, a special four-barrel Rochester carburetor, and less-restrictive exhaust. What really made the GSX fly was its torque, rated at an incredible 510 foot-pounds at just 2800 rpm, more than anything else in its class. Helping in the horsepower-to-weight department was the fact that the "thin-wall" 455 engine was much lighter, for example, than Chevy's big-block 454 and only slightly heavier than Chevy's small-block 350.

Called by many "The most powerful muscle car ever built", the 1970 GSX was available in only two colors - Saturn Yellow and Apollo White, both with black interiors and contrasting tape trim. The GSX was fitted with front and rear spoilers as standard equipment; along with bucket seats, a floor shifter, wide oval tires, quick ratio steering and anti-sway bars. Buick only produced 678 GSXs in 1970; just 479 carried the Stage 1 performance package which included larger valves with stronger springs, a high lift cam, ported heads, a special carburetor, and a low restriction exhaust. The introduction of unleaded gasoline and tightening emission controls saw horsepower ratings begin to drop in 1971, but the GSX remained a very strong performer for its day.


THE MOTORCAR OFFERED

This stunning Saturn Yellow Stage 1 GSX coupe was the 117th example produced in 1970. Heavily optioned, it was one of just 199 GSXs factory-equipped with a four-speed gearbox with floor shift. It also had power steering and front disc brakes, a radio, and carried a sticker price of $3864.17.

Delivered to Del-Ton Buick in Tonawanda, New York, the car was first sold to Legendary Motor Car Company in Halton Hills, Ontario, Canada. After passing through several owners, this GSX had been fully restored by 2007 and garnered a Gold award at the Grand Sport Club of America's annual competition at Bowling Green, Kentucky. In October, 2012, the car was offered by Chris' Auto Connection in Moorpark, California. The consignor acquired the car soon afterward.

Showing just 42,703 miles, this Stage 1 GSX is supplied with its original radio, spare, jack, tools, and extensive documentation. It is ready to please its next owner and is certain to be a standout at any automotive gathering.
